Title: Process of extracting and concentrating vitamins
IPC: A61K31/16
Filed: 1935-10-08
Abstract: Vitamins are extracted from natural materials such as fats and oils by acting directly on the raw material with a solution of acetone and hydrocarbons either simultaneously with, or subsequent to, the addition of a saponifying agent, and without the previous separation of the saponifiable and unsaponifiable matter. Modifications of the above process which are described comprise: (1) the saponification of the raw materials in the presence of acetone, followed by extraction with a hydrocarbon solvent after saponification is completed; (2) the saponification of the raw materials in the presence of a hydrocarbon solvent, followed by addition of acetone after the saponification is completed, and the removal of the hydrocarbon layer containing the vitamins; (3) the saponification of the raw materials in the presence of both acetone and a hydrocarbon solvent, followed by the removal of the hydrocarbon layer containing the vitamins when the saponification has been completed.  The term " hydrocarbons" includes any hydrocarbon spirit liquid at ordinary temperatures and having a boiling point not exceeding 175 DEG  C.  Examples are benzene, benzine, and petroleum ether.  It is preferred that the hydrocarbon oils used for extraction purposes in the present invention should be first subjected to a purification treatment comprising mixing the hydrocarbon with heavy oils and then distilling off the hydrocarbons ready for use.  It is stated that noxious impurities may be removed in this way.  A preferred purification comprises the addition of 20 kilos. of a vegetable or animal oil, or a pure heavy mineral oil to 80 kilos. of hydrocarbon, followed by the distillation of 70--75 kilos. of the hydrocarbon.  The residue is rejected.  In examples: (1) liver oil is saponified with aqueous potassium hydroxide in the presence of acetone either under pressure or under reflux.  After saponification, the vitamins are extracted by a hydrocarbon solvent such as benzine, preferably added in the proportion of one volume of benzine to one volume of solution.  On the second and subsequent extractions it is usually necessary to add more acetone to avoid the formation of emulsions; (2) the saponification is performed in the absence of acetone, which is then added in an amount sufficient to dissolve all the soap.  The solution is then treated as in example (1); (3) the raw material is dissolved in benzine, saponified, acetone added and then the extraction performed as in example (1); (4) the oil is saponified in the presence of acetone and petroleum ether.  After saponification, the extraction is carried out as in example (1).  Specifications 362,023 and 393,883 are referred to.

Title: Electric switch
IPC: H02P1/42
Filed: 1959-08-18
Abstract: 895,107. Control of A.C. motors; electromagnetic switches. ELLENBERGER & POENSGEN G.m.b.H. Aug. 18, 1959 [Sept. 26, 1958], No. 28180/59. Classes 38 (3) and 38 (5). A split-phase motor is started by closing a main switch (not shown) to energize main motor windings 55, 56, and starting winding 59, the circuit to a heating coil 9 being also completed at this time. After the operating speed of the motor is reached, bimetallic strip 6 is bent so that contact 12 engages contact 14 on spring 13, whereby relay-coil 27 is energized to attract armature 30. In this position, the starting circuit is opened at contacts 32, 35, and the heating-coil 9 is de-energized to return the strip 6 to its original position. A holding circuit for the relay-coil 27 is completed through contacts 33, 36. When the main switch is opened, a spring 31 returns the armature 30 to re-close contacts 32, 35, and to open contacts 33, 36, thus restoring the system to its original condition. The spring 13 is bimetallic to compensate for ambient temperature, and cooperates with a grub-screw 20 for setting the distance between the contacts 12, 14. In another arrangement, closure of the main switch energizes the main motor windings (connected to strips 69, 70) as well as the starting winding (connected to strips 5, 69). The heating-coil 9 is also energized and the bimetal 6 is bent until it engages stop-member 72 on spring 62. This disengages contacts 63, 64, so that resistor 65 is connected in series with the coil 9 to reduce the heating current. Further bending of the strip 6, at a slower rate, engages contact 12 with contact 14 on spring 13 to energize relay-coil 27. The armature 30 is attracted to separate contacts 32, 35, and to close holding contacts 33, 36, so that the starting circuit and the heating-coil 9 are deenergized. The strip 6 cools and returns to its original position, thus releasing the spring 62 to re-engage contacts 63, 64. The armature 30 co-operates with a contact 75 for bridging signal contacts 80, 81, and 78, 79, alternately. The spring 62 consists of a bimetal and resistor 65 forms a heating-coil therefor, whereby the contacts 12, 14 are engaged after the same delay regardless of the distance between the contacts and the temperature of the strip 6 when the motor is switched on.

Title: Improvements in or relating to card filing systems
IPC: B42F19/00
Filed: 1965-07-06
Abstract: 1,113,351. Index tabs. R. P. GLOWIAK. 18 Aug., 1965 [6 July, 1965], No. 28554/65. Heading B6E. An index tab 33, Fig. 2, comprises a transparent part 34 with adhesive on the back for attachment to an index card and an opaque part 35 for receiving indexing indicia. An additional part 30, which may be opaque or transparent, is attached to the tab 33 and is folded back on to the tab after the latter has been secured to the card. A slit may be provided along the fold line to facilitate folding. The slit may completely separate the two parts, in which case a previously-applied overlay of transparent synthetic plastic material holds the parts 30, 33 together. A set of ten of such tabs is formed by attaching a transparent cellulose acetate film 12 by a pressure-sensitive adhesive 13 to a kraft-paper backing sheet 11 and die-cutting the film around the peripheries of the tabs so that the film parts comprising the tabs can be easily detached. The opaque parts are formed by printing with a white colour and then overprinting with a distinctive colour on a portion of the opaque parts, i.e. the portions occupied by the unit parts 0 . . . 9 of reference numerals. The first or tens numeral and the distinctive colour are the same for all the tabs of a set. By using ten sets of tabs with different tens numerals 0 . . . 9 and corresponding different distinctive colourings, cards which may have an account number within e.g. the range 2000-2999 may be indexed for easy selection. For this a tab is selected for each card corresponding to the tens and units, of the account number on the card and is attached to the card in the column position corresponding to the unit number. If a card with a particular account number is to be picked out from the tabbed cards, the operator has to look at cards with tabs in the column corresponding to the unit part of the number, and select cards with the distinctive colour corresponding to the tens part of the number. This leaves only a few cards to be scanned for the hundreds part of the number. Scales 23, 24, Fig. 2, may be provided on each set of tabs to facilitate the correct positioning of the tabs on the cards. Receptacles or covers for sheets.-A cover for holding sets of tabs comprises two frames 55, 56 and 57, 58, Fig. 6, hingedly connected by a cover sheet 71 . . . 75 which extends around the frames, and divided into compartments by cross-pieces 61, 62. Manufacturing processes.-An arrangement for making sets of tabs is described, wherein acetate film fed from a roll (90, Fig. 8) and backing paper fed from a roll (91) pass to pressing rollers (94, 94a) after pressure sensitiveadhesive has been applied (at 92) to the film and dried by a heat bulb (93). The white colour is applied to the opaque areas by an offsetprinting machine (95) and two coatings of the distinctive colour by two offset printing machines (101, 102). A sealing coating to protect the coloured parts may be applied at (103). Subsequently, the peripheries of the tabs may be die-cut (at 104) and the material cut into set lengths.
